Spinal fixation devices provide stability and restore alignment after fractures, degenerative disc disease, infection, tumor, and congenital deformities. They provide immediate stability. However, if no bony fusion occurs they eventually fail due to prolonged stress and fatigue fractures in the metal. Fixation instrumentation needs to be assessed for adequate positioning and anatomic alignment of the fused segments on the initial radiographs. Follow-up radiographs should be scrutinized for instrumentation complications such as failure of fusion, instrumentation loosening, migration (subsidence), and component fracture. Management varies, depending on the nature of the complication. Generally instrumentation will be removed and a revision will be undertaken. In case of instrumentation infection a washout will be performed and antibiotic therapy will be instituted.
